SPECIFICATION forming pm of Leiters Patent No. 667,910, antearbmary 12, 1901.

Application filed Jiune 26, 1900.

ToaLZ whom, it may concern.' Y A Be it known that we, WILLIAM A. HATCHER and JAMES W. PACKARD, citizens `ofgthe United States, residing at Warren,in the county of Trumbull and State of Ohio,rhave invented certain new and useful-,Iinprovements iu Mixers and Vaporizers, of which the following is a specification. This invention relates to hydrocarbon-'motors, and moreparticularly to mixers and vaporizers for this class ofmotors.

The object ofgthe invention is to provide asi mple apparatus for effectivelylregulating` the admission of .gasand air to the mixingchamber.

`The invention will be described in detail in -connection with the accompanying drawings,.`

in whichy Figure 1 is a side view of so much of the apparatus as is necessary to illustrate the invention. Fi 2 is a central sectional view of igs. 3 to 9,inolusive, are details of the apparatus shown .in Figs. 1 and 2. Figs. l-to lginclusivq-illustratea inodfied form ofthe iventieu" .fRefen'ing first toFigs. 1 to` 9, inclusive, 1'

indicates the Storage-reservoir, from which the gasoleue-passes thraugha tube 2 into the tank or vessel 3. The supply-of hydrocarbon to the tank 3 may be' positively shut oi or- 'regulated by a valve 4. I-t is also automatically controlled by la valve 5, 'carriedby a oat 6 inrtank 3. In t-he top of the tank 3 is a plunger 7, bymeans of which the iioat' may be positively depressedwhen it i-s desired to fill the tank with fluid. The hydrocarbon flows from the tank 3 througha passage 8 and upward through small passages 9, Figs.

2 and '4, into a cylindrical chamber 10. In

.the lower part of this chamber is a threaded opening into which is screwed-a'stem 1l, Figs. 2 and 7. Beneath the stem 11 is a cavity or well 12, in which dirt may accumulate, the bottom of said well being in -a removable cap 13. The upper end of the Wall of chamber 10 is beveled, forming a conical seat fora oonical head 14 upon the stem l1. This head is provided with -a series of sm'all peripheral grooves 15,'Figs. 31nd 7. The float is so pro#` portioned that it permitsthe gasolene in the tank and in the chamber 10 to rise approxiserinnmz'nais. (nomas.)

Imatelyl to a level with the lunder side of the head 14, as indicated bythe, line a: w, Fig. 2.

The air enters through a pipe '16 and through openings 17 in the side ofia cylindrical' jacket 18,-.Which surrounds the chamber 10 at some' little-distance from its wall, Figs. 2 and 6. The jacketlS is provided with an offset portion 1 9, forming a seat,'for a purpose` 0o be referred to hereinafter, and a cylindrical'eitension 20 above said seat. In the extension 20 are openings 21. Thejacket or pot 18 is also provided with a iiange 22, which fits the in*-` ner wall of the casing 23, in which the jacket is located. `Within the jacket 1S and restiugupon the seat 19 ,is an air-valve 24, comprising a cylindrical portion 25, which has a working fit in the lower. part of the jacket,

a'cylindrical part 26, which has a working it in the upper part of Athe jacket, and an oiset 27 between said .partsfadapted to. rest4 on the seat 19 of the jacket. The air-valve Ialso has an inwardly-projecting ange' 2S,

wh-ichiits close up tothe wall 10a of the cham-v ber 10.A In the uppercylindrical portion of the air-'valve are a' series of openings .29. When the-valve is in itslowest position, as shown in Fig.' 2, the openings 29 do not register withv the openings 21 in the jacket; but when the air-valve is sufficiently raised communication is opened between the air-chamf ber su rroundiug the jacket th rough the openings 21 and 29 .and the mixer-chamber 30.

lThe mixer may be provided with any suitable number of screens 3l or other devices to thorin the pipe 32 in the` usual manner, the effect of which is to draw into the mixing-chamber a charge of gasolene, which is sprayed 1n "through the openings 15, and to simultaneously raise the air-valve and permita charge of air to enter at the inner edge of the ange 28,-'thejair and o il coming into intimate contact and,being carried up. into the mixer to- IOO gether. When the engine is taking light covered.

vcharges of themixture,the air-valve is raised but slightly and the openings 21 are not uu- Wheu, however; the draftupon the mixture is stronger, the air-valve is raised suiilciently to uncover more or less of the openings 21, so that air ma)1 enter-through said openings, as well as through the central openingr of the iauge28. The air-valve falls back to its seat and closes all of the air-inlets after each charge of mixture is drawn into the cylinder. We have found an apparatus constructed as above to regulate automatically the charges of air and hydrocarbon in a very satisfactory manner.

lin Figs. lll-.to 13, inclusive, we have shown the same devices as in Figs. l to 9, inclusive,

' 'aud'in addition we' have'shown means for .positively moving the air-valve as follows:

A\pipe 32, leading from the mixing-chamber 30 to thecylinder, is normally closed by a valve, said valve being drawn to its seat by a spring 34, surrouudingits stem 35. The maximum opening of the valve 33 is regu- 1 lated by'a threaded pinion or nut 36, which is adjustable upon a threaded extension 37 of stem 35. At each opening of the valve the nut 36 abuts against a iixed seat 38 on the :valve-casing, and the position of the nut regulates'the opening'of the valve, as will be readilj,1 understood'. The nut 'or pinion 36 is 4,adjusted by means of a sector-gear 39 on an arm 40 of a rockshaft4l, the said rock-shaft being controlled in any suitable manner,

either automatically or by hand-lever. The devices for controlling the rock-shaft form uo part of the present invention.

" arms are operativel7 connected together by Connected to the stem 35 is an arm 42, and connected to the air-valve is an arm 43, which means of links 44 and 45 and an intermediate 1 right-angled elbow-lever 46.

It will be seen that the'devices shown in Figs, 10 to 18, inclusive, effect the-opening of the air-valve 24 positively and in proportiou to the opening of the mixer-valve 33, the

'opening ofrboth of said valves being'` under the control of a sector-gear 40.

Having describen. our invention, what we .claim as new, and desire to secure by Letters Pateut, is-

- 1. In a hydrocarbon-motor, the combina- I tion of the chamber 10in communication with the .giacciono-supply, the series of openings in the top of said chamber, and the freely-moving air-valve having an inner flange located close to said-openings when the valve is closed.

2. In a hydrocarbon-enfi'lnm the combination of the chamber l0 communicatiupr with the gasoleue-supply, and provided with a series of small openings at itsupper end, a jacket surrounding; said chamber aud separated therefrom, the lair-valve sliding' in said jacket und normally-closing the space between the jacket and the chamber, andthe mixer above said air-valve, for the purpose set forth.

3. lu a h vdrocarbon-engine, the combination with the gasolcue-chamber 10 having a series of perforatious in its upper portion, the

jacket su rrounding and soparatediom said-- chaniber, means for admiting air to the lower portion of said jacket, a series ofjopenings inf saidjacket comm unicatiug,` directly with the mixer, andau .air-valve sliding within the vjacket and arranged to norn'iallyclosc said openings,fsaid air-valve beingprovided with opeuings'to register with the openings ini-he jacketwhen the air-valve is raised.

LL.
